- AKA: John I of Oldenburg
Biography
Johann I Graf von Oldenburg in Oldenburg und Delmenhorst, Count of Oldenburg, was born circa 1204 in Schloss Oldenburg, Oldenburg, Lower Saxony, Germany to Christian II. von Oldenburg (c1180-1233) and Agnes von Altena (c1184-c1231) and died circa 1270 of unspecified causes. He married Richza von Hoya (c1240-c1287) .
His father, Christian II, had ruled jointly with his uncle, Otto I. After Christian II died in 1233, Otto I acted as guardian for the underage John I. When John I came of age, he ruled jointly with Otto I. After Otto I died in 1251, John I ruled alone.
In 1244, Otto I and John I together founded the Cistercian Rosenthal monastery in Menslage. In 1251, the monastery moved to a fort in the Börsteler Forest, which John I already owned.
In 1258 and 1259, he fought in the Bremen Prince-Archbishopric Feud on the side of his cousin Hildebold of Wunstorf against Rüstringen, Östringen and Stedingen. When the feud had ended, he kept the territories he had conquered.
After a dispute with the City of Bremen, he had to cede the castle in Berne. As a replacement, John I and his uncle built a castle in Delmenhorst, which provoked a strong reaction from Stedingen.
Like his predecessors, he had many disputes with his relatives, the Counts of Oldenburg-Wildeshausen. Ultimately, their county was divided between the bishops of Münster and Bremen. This resulted in Oldenburg and Delmenhorst being almost completely surrounded by these territories, and led to centuries of disputes between the Counts of Oldenburg and the two Prince-Bishops.
